Appncauon filed. January v, 19241.. serial No. 684,752.

To all 1071.071?, t may @orme/ru:

Be it known that l, llan'riin E. l.Vonnr-niiir, a Citizen of the United States, and a resident of New York, in the county of New Yori; and State of New York, have invented certain new and useful Improvements in Burners, of which the following is asoeciiication.

This invention relates to fuel oil'burners, particularly the kind adapted to be used "for domestic installations in which the oil is fed to the burner from a small tank by gravity, and in which air for combustion is automatically supplied by the draft in the furnace, whereby all such accessories blowers, pumps, motors, etc., are eliminated.

lt is one of the particular objects of the invention to provide a burner which will te'ive a maximum amount of heat in propor--V tion to the oil consumed.

Another object is to provide means which deflect the flame, if desired, partially towards the sides or the roof of the fire* box of a boiler within which the burner is placed, thereby causing a quicker heatine' ofthe water or air in the boiler.

A further object is to surround the oil pipe within the burner with an air j )assage for cooling purposes to reduce carboniza tion of the oil.

A still further object is to so arrange the component parts of the burner,Y that the same can easily and readily be cleaned, when necessary, without breaking any joints with in the burner, so that this can conveniently be done by a person relatively unskilled in the handling' of mechanical devices.

Further objects are the provisionV Vof 'a protecting housinfr over the valve mechanism of the burner, a clean-out connection between its valves andthe oil outlet within the burner, and the particular arrangement of piping between the burner and its valves so that erectingthe same may be ao-y complished with the least possible eXpense.

Still other objects will become apparent in the following,- speciication and the accompanying drawing which shows a preferred vform of a burner embodying the aforesaid improvements, and in which Fig. 1 is a plan view of the burner;

Fig. `2 is a vertical longitudinal crosssectional view throng-fh the burner, talren. along the planeof line 2-2, in Fig. 1; n

Fig. 3 is a rear' elevation of the valves of the burner and the protecting housing;

Fig. 6 is a similar view alonn the plane of line 6 6, in Fig. 1.

Like characters of reference denote similar parts throughout the several views and the following specifications:

10 is a grate within a furnace of which 11 is a front wall, and 12 an ash door opening.

13 is a burner base of substantially circular configuration, slightly smaller at its upper end than at its lower end which rests upon the grate l0. rlhe top of the base is bowl shaped at 14, and has, preferably, six tubular projections 15 extendingV therefrom to a plane in line with the top of the base, where the projections are somewhat reduced in diameter and project slightly above base 153, 16, forming,` shoulders 17 in line with the top of base 13.

llt the lowest portion of the bowl shaped too 1dis an upwardly extending` tubular projectionl within which a tubular nij'nple 19 is connected integrally by means of ribs 20. Nipple 19 is threaded interiorily to receive at its top a vaporizer 21consisting,` of an externally threaded stem 22 havingl a` central duct 23, and an umbrella-shaped top 2e. The upper surface of top 24 is provided with shallow, concentrically disposed, grooves 25.

2G is an air manifold consisting of elbow likeV branches 27, telescoping over tubular extensionsl and resting` on shoulders 17 of the base 13. Branches 27 converge into central chamber 28 which is provided with a downwardly directed outlet 29, in linewith vaporizer 21 and terminating a short distance above it. At the outside of the manifold 26, in its center and top,is a lug 30 having a hole 31. Near the inte sections of the elbow branches 27 at the top j of the manifold are sockets 32. ,Y

` 33 `are deflector plates, placed at theV top of the air manifold 26, at, preferably, both `v sides of the burner, as shown in Fig. `1.

These plates are shaped segmentally,and,

in case of a six branch manifold, are each Y equal to oneethird of they area of a circle.; The underside ofeach plate is provided with two pins'l which t loosely within is larger than that of the burner bese, zii o.

. the furne ze,

'sockets 32 of the mani-fold, and with three flat lug-s 35, in staggered relation to the pins 34, which rest upon the top of 'the three elbows Q7' over which the plate is laid. The diameter of these plates when measured in position and concentric with the burner therefore extends beyond the base :it both sides. lYhile the inner port of eerh plete where it rests upon the iiizuiifold is flot at 36, its outer port is tilted et en ongle at 23?. 3S are lugs with holes 39, et the top of plates 33.

Screwed into nipple 19 of buse i3, is :i pipe Ll() which projects through the grate in and tern'iinetes ey little below it, where it screws into an overflow pen itl of round cup shape. el-Q is overiow pipo screwed into bowl lllof bose 15%, slightly above its lowest point. This pipe is litt/ed. 0r bent orer at 4:23, within the lower part of the bose and `above the grote, to run closely and parallel to pipe ll- O end terminates ai little above, but within the outer circumference, of the overflow pen` E. The rou,- son for running; the lower end of this pipe closely to pipe l0, to fac'litcte wie placing of the beso upon. the grote with both pipee l() and 4:3 projecting' through the grote bers. At Lthe underside or overflow per. il ere two bosses, the one 44, being in centrolelirgimentwith pipe 4:0, is threeded to receive :in oil supply pipe et right to pipe 10, and the other 46, being threaded to receive an oyerllow pipe il?, Substantially parallel to pipe and which pipe 41:7 is connected to the upper cup shaped port of overflow pen .l-l by means of o duct 48.

'At the end of oil pipe outside of the furnace, is screwed 'l' connection 49, its outlet et rioht angles thereto beingclosed by n. plug` o0, its other outlet being; connected` to am oil rcguleting valve :il of coriv ventionzil uoecle valve desiign. Regulating valve 5l has an elbow connection et its lower inlet which connects it. r-.f'itli ai safety trip Valve 52 which is e conventional type of spring,T opergitcd sluit-olf Yelre, provided with lever` to the end of which is suspended :i trip cup fifi. rihe end of overflow pipe 47'? is bent dowower lly and pitched :it a. slight angle to terminate e little above the open top of the Safety trip cup file. 55 is :in oil feed pipe which connects the safety trip valve with a feed tank.

Fitted over the rear of the safety trip valve V52 and extending` frontwerdly (toward the furnace), beyond its centerline, is o. protecting housing; 56, substantially lle shaped iu cross-section. y lts top 57 is closed, :ind its bottom 5S is 'dat to form c. support for the housing` on the floor. 59 fire recesses, ot both Sides of thehouf to erieble the same to be fitted orer the pu connections to und from the ety trip no other fen Valve. Vithin the housing, at its bottomr` is fitted :in open pan 60, )roz'ided with n..

frontwardly extending;l luie` fl2 :it its top.

Gillis :in asbestos ped placed within the The operation of the device is, zu; follows:

@il ie admitted by wey of feed pipe through the valves (the e'ffetjy trio beingwide open, the oil r i slig itly only), pipes 4:5 el?, lowed to dribble over the top 2l of veporier 2, lillinp` its grooves 25, and accumulato :it the bottom of the bowl le of the bui There the oil crates esbcotof: which is then ig @ed by ineens of lllithin :i fev. minutes. 'the ".*riporizer so hot, through the action of the flzlme from pod 52, that the oil .in grooves 25 it: op -rized and is mixed with the oir induced by the draft in the furnace through bese i3, extensions l5 .find lr6, end elbows' il? of iniiiiifolil 2G, end dif-charged tlireuglr outlet 29. This results in combuetior, :ind cerises strong; and steady llame to eurround the nieiiifold and issue from between its bronches into the tirebof; of the furnace. The ii'itensity of the llame is reo'ulated by means of the oil regulating volvo 5l. It will be noted that the flame, while passing; around the manifold, automatically preheats the oir supply whereby V.grooter ellieiency in combustion is achieved. The Home, after having passed through between the branches of the oir manifold, is deflected et both sides of the tirebox by the plates while io front end beck the Home is projected to the roof. This results in e rcrj-y creo distribution of heet.. By means; of these platee, the burner is merlo adaptable lo ,'zriyinjr types; of furngices, ineomuch zur. wliere :i strong flame is required :it the rezo of the Firebox, the two platee may be laid onto the manifold closely together :it the front of the burner, for which reason sockets have been provided between the intereecti n of each. branch of the manifold. This, in connecion with the segmental shape of the plates permits the `some to be placed in any oesired positie-e ou top of the menifold, end, if preferred, three plates` may be used, form- L0 ing e closed circle at the top. ln practice, the method of placing the plates the top by menne of pins and lugs, in staggered relation to euch other, has been found. perH ticularly edvzrntzwcous, because, in the 4tirst place, they are in this manner perfeiiftly balanced on top of the nmnifold, requiring teiiinp; member-e, such as. ocrcwf: end con tierefore with the placed in position, und, Secheee.

l 7 least trouble be Va practically noiseless operation.

meanesondly, the distance between the lower sides of the platee and the 'top of the base is so much larger than the flame outlet between. the branchesI of the manifold, that there is no restriction to the flame, which results in Tl`he up wardly tilted outer ends of the plates greatly augment this feature.

`In the event that there be an oversupply of oil, or in other words, the burner should not vaporize alloil fed to it, or, if the flame should have been extinguished for various reasons, oil will overflow through pipek 42 into pan 4l, thence into pipe 47, andV gradu ally fill cup 54 of fthe safety trip valve 52.

As soon as this cup is full, its'weight will press lever 53 down, as shown in dotted lines in Fig. 2, and thereby release a spring operated disc within the valve 52 which is thereby closed and shuts ofl1 the oil supply to the burner. Protecting housing 56 is provided to prevent injury to the safety trip valve and its cup, and to prevent spilling of oil on the floor. Drippingsfrom the trip cup 54 will accumulate in pan G0 at the bottom of the housing which pan can be emptied easily and safely.

The structural characteristics of the burner are such as to enable the same to be cleaned easily and quickly by persons unskilled in the handling of mechanical appliances. A rod can easily be inserted in holes 89 of lugs 38 and the plates be lifted off. There are no catches or hooks of any kind at the underside of these plates which simply rest on the top of the manifold and are guided in position and there held, in proper balance, by pins 34 and lugs 85. After having removed plates 33, in a similar manner, the manifold 26 may be lifted off by insert# ing a rod or hook into hole 3l at its top. This exposes the vaporizer 2l which can then be scraped off or unscrewed for cleaning, if necessary. Plates and manifold may easily be cleaned with a stift1 brush or rag. In case of clogging of the oil supply pipe within the burner, the oil regulating valve 51 should be closed, and plug 50 removed from "l" 49. A flexible wire may then be inserted, or, a hand air pump may be screwed in place of the plug, when a few strokes of the pump will clean out the pipe and blow out any obstructions through outlet 23 of the vaporizer.
